Abstract (en)
[origin: US4976763A] The installation for curving or bending to convex form and tempering a sheet of glass (1) comprises means for heating the sheet and means for bringing this latter between elements (3, 4, 6, 7) for shaping said sheet. One of the series (3) of elements has a surface (3a) which is intended to come into contact with one of the faces of the glass sheet (1). The other series of elements (4, 6, 7) has a stationary portion (5) to which is attached at least one movable portion (6 or 7) which is capable of pivotal displacement through an angle corresponding to the curvature to be given to the glass sheet.
